Key actives
Product Summary
"Trinny London - Overnight Clarity" is effective for: Evens skin tone, Anti-aging, Moisturizing and Anti-blemish
Ingredient callouts
- A good concentration of Niacinamide (4.40% - 5.40%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
- This product contains an effective form of Retinoids (vitamin A): retinal 0.40% - 0.60%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily.
- Potassium Azeloyl Diglycinate (3.10% - 3.80%). It is a derivative of Azelaic Acid. It is less studied than Azelaic Acid, but the available research suggests that it also can be effective in reducing skin redness, hyperpigmentation and blemishes. There are claims that it is more bio-available and more effective than azelaic acid, but no comparison study is available. Potassium Azeloyl Diglycinate is better soluble in water compared with Azelaic Acid. Because of this property, products with Potassium Azeloyl Digclycinate can have a nicer texture.
- Humectants (sodium lactate 0.10% - 0.20%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
Anti-aging
What does the product description say?
Starting to notice those first fine lines and still struggling with pesky hormonal breakouts?
Source: N/A
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains retinal, niacinamide.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
One step removed from the biologically active in skin form of vitamin A. Once converted to the retinoic acid in the skin, retinal is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. Concentrations of 0.05% and 0.1% are shown to be effective. It can, however, be irritating
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Anti-blemish

A derivative of azelaic acid. It is obtained by reacting the chloride of azelaic acid with two molecules of glycine (an amino acid) and potassium hydroxide. It is less studied than azelaic acid, but the available research suggests that it also can be effective in reducing skin redness, hyperpigmentation and blemishes.

Anti-oxidation
This product contains antioxidants (glutathione) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
A peptide that can help neutralize free radicals in skin and reduce melanin production resulting in skin lightening effect and reduction in hyperpigmentation. It can also help attract moisture to the upper layer of the skin
A berry extract that can have some anti-oxidant properties. It helps to preserve product formulations and improve their smell. It can be irritating
A plant extract that can help to attract water to the upper layer of the skin and might have some anti-oxidant and anti-inflammatory properties

Evens skin tone
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: retinal.
In addition, this product contains glutathione, niacinamide, potassium azeloyl diglycinate. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

Moisturizing
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
sodium lactate, glucose.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, coco-caprylate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
Helps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product
